-2 18/25x+y:1 1/6-99z при x=-4 4/17,y=-25 2/3,z=-0,02

Answer 1

Ответ:

Пошаговое объяснение:

=-2 18/25*(-4 4/17)+(-25 2/3:1 1/6)-99*(-0,02)=-68/25*(-72/17)+(-77/3*6/7)+

1,98=288/25+(-22)+1,98=11,52-22+1,98=-8, 5

Answer 2

To evaluate the expression when x = -4 4/17, y = -25 2/3, and z = -0.02, you'll need to substitute these values into the given expression:

Expression: -2 * (18/25)x + y : 1 + (1/6 - 99z)

Substitute the values:

x = -4 4/17 = -4.235294118... y = -25 2/3 = -25.666666666... z = -0.02

Now, calculate each part of the expression step by step:

Step 1: -2 * (18/25)x -2 * (18/25) * (-4 4/17) -2 * (18/25) * (-4.235294118...) = 2.8235294118...

Step 2: y : 1 -25 2/3 : 1 -25.666666666... : 1 = -25.666666666...

Step 3: (1/6 - 99z) (1/6) - 99 * (-0.02) (1/6) + 1.98 = 1.983333333...

Now, add the results from Step 1 and Step 3 and then subtract the result from Step 2:

2.8235294118... + 1.983333333... - (-25.666666666...) = 2.8235294118... + 1.983333333... + 25.666666666... = 30.4735294118...

Rounded to a reasonable number of decimal places, the result is approximately 30.47.
